Abstract
A band conveyor roller new-type special bearing includes a bearing outer ring (1), a bearing inner ring (2), a steel ball (3) installed between the outer ring (1) and the inner ring (2) and a bearing retainer (4); the bearing is characterized in that both sides of the bearing are inserted with a contact-type rubber sealing cover (5) or a non-contact type steel sealing cover (6), and the bearing retainer (4) is a non-metal retainer which is provided with anti-clamping effect.
Description
Technical field
The utility model relates to a kind of bearing, specifically is a kind of Belt Conveyors carrying roller new exclusive bearing.
Background technique
Belt Conveyors is widely used in industries such as power plant, colliery, steel mill, cement, harbour; the carrying roller use amount of Belt Conveyors is very big; its Environmental Conditions is comparatively abominable; it is more abominable particularly to reach the special occasions environment under the coal mine; the damage major part of carrying roller is that the damage owing to bearing causes; the damage of bearing is except that the too early inefficacy of carrying roller sealing configuration, and its bearing also lacks the self-protection function.
The KA series carrying roller special bearing that uses at present, though have anti-jamming function, non-watertight, dustproof, the working life that is difficult to improve bearing.
Summary of the invention
The purpose of this utility model is to improve the self-protection ability of bearing, and a kind of Belt Conveyors carrying roller new exclusive bearing anti-jamming, the waterproof and dustproof function that has that adapts under the rugged environment work is provided.Improve the working life of Idler bearing to greatest extent.
The utility model is realized with following technological scheme: a kind of Belt Conveyors carrying roller new exclusive bearing, comprise bearing outer ring, bearing inner race, be installed in steel ball and retainer between outer ring and inner ring, be inlaid with contact-type rubber closure or contactless steel sealing cover in the bearing both sides, retainer is the nonmetal retainer with anti-jamming effect.。
The structure that described bearing both sides are inlaid with the contact-type rubber closure is: in bearing outer ring endoporus both sides, bearing inner race outer peripheral surface both sides all are processed with the groove of inlaying sealing cover, rubber closure is embedded in the groove of the inside and outside circle of bearing.
The structure of the contactless steel sealing cover in described bearing both sides is: be processed with groove in bearing outer ring endoporus both sides, the steel dust cover is embedded in the groove of brearing bore.
The beneficial effects of the utility model are: bearing with anti-jamming function and the bearing with waterproof and dustproof (2R, 2Z) function organically are blended together, form carrying roller new exclusive bearing.Dustproof, waterproof, anti-jamming, long service life.Substitute former KA series carrying roller special bearing, can improve greatly the working life of carrying roller, and then reduce the operation cost of Belt Conveyors.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 adopts contact-type rubber closure structural representation for the utility model;
Fig. 2 adopts steel dustproof cover structure schematic representation for the utility model.
Among the figure: 1, bearing outer ring, 2, bearing inner race, 3, steel ball, 4, retainer, 5, rubber closure, 6, the steel sealing cover.
Embodiment
As shown in Figure 1, adopt contact seal, also claim two glue envelope types.Corresponding groove all is processed into so that sealing cover 5 to be installed in its bearing outer ring 1 endoporus both sides and bearing inner race 2 outer peripheral surface both sides.What sealing cover 5 inner edges contacted with groove on the bearing inner race 2 is light and heavy, though be related to seal degree, also directly has influence on rotational resistance big and little of bearing, needs appropriateness to grasp.In the present embodiment, rubber closure 5 its materials are that synthetic rubber adds iron packing ring.Synthetic rubber can be used nitrite rubber (NBR).When operating temperature is had relatively high expectations, can adopt polypropylene (ACM), fluoroplastic (FKM) and silicone (MVQ) synthetic rubber.Rubber closure is a contact-type, plays the effect of water proof and dust proof.
As shown in Figure 2, adopt noncontact seal, also claim two iron envelope types.Be processed with groove in bearing outer ring 1 endoporus both sides, bearing inner race outer peripheral surface both sides then must not process groove.Steel sealing cover 6 is embedded in the groove of brearing bore.In the present embodiment, Z-shape steel system sealing cover 6 is stamped to form by sheet metal.The steel sealing cover is both non-contact types of open type, has the dust-tight effect, and waterproofing effect is relatively poor.
The inside play of Idler bearing all adopts C4 or C3 level, and is smooth to guarantee the bearing rotation.
Claims (5)
1, a kind of Belt Conveyors carrying roller new exclusive bearing, comprise bearing outer ring (1), bearing inner race (2), be installed in outer ring (1), steel ball (3) and retainer (4) between inner ring (2), it is characterized in that: all be inlaid with contact-type rubber closure (5) or contactless steel sealing cover (6) in the bearing both sides, retainer (4) is for having the nonmetal retainer of anti-jamming effect.
2, Belt Conveyors carrying roller new exclusive bearing according to claim 1, it is characterized in that the structure that described bearing both sides are inlaid with the contact-type rubber closure is: in bearing outer ring (1) endoporus both sides, bearing inner race (2) outer peripheral surface both sides all are processed with the groove of inlaying sealing cover, rubber closure (5) is embedded in the groove of the inside and outside circle of bearing.
3, Belt Conveyors carrying roller new exclusive bearing according to claim 1 and 2, it is characterized in that described rubber closure 5 its materials are that synthetic rubber adds iron packing ring, synthetic rubber comprises nitrite rubber (NBR), polypropylene (ACM), fluoroplastic (FKM) and silicone (MVQ) synthetic rubber.
4, Belt Conveyors carrying roller new exclusive bearing according to claim 1, the structure that it is characterized in that the contactless steel sealing cover in described bearing both sides is: be processed with groove in bearing outer ring (1) endoporus both sides, steel sealing cover (6) is embedded in the groove of brearing bore.
5, Belt Conveyors carrying roller new exclusive bearing according to claim 1 is characterized in that described retainer (4) is that nonmetal mould is annotated the macromolecule engineering plastic production, as nylon or glass-fiber-reinforced polyamide 6.6 etc.
